How do you upgrade to a newer OOS version with official TWRP - OnePlus 6 Questions & Answers

Hey guys,
I'm not sure if any one of you have tried doing this without getting a PC involved. Since there is no recovery partition and recovery is part of the boot partition. How would you go about upgrading to a newer version.
Would you flash the full OOS zip(Let's say the 5.1.8) through TWRP and then you would patch the boot image through TWRP without booting back into system.
Or would you go about upgrading through the settings->updates->upgrade, reboot to system, reboot to fastboot and go through the TWRP flashing again by booting the twrp and then patching the system with twrp?

There are several threads here explaining these questions...
With PC:
Update via settings. Then directly reboot to fastboot to boot twrp. There flash twrp.zip and magisk.zip. Reboot system.
OR
Without PC:
Update via twrp then directly flash twrp.zip. Reboot to twrp (the installed one then gets loaded) and flash magisk. Reboot system.
It's up to you what option you choose.

So correct me if i was wrong i have to download full rom package and then i have to flash it via twrp and flash twrp installer zip(not the twrp image) then flash magisk and reboot so is this process correct and also will i loose data like photos on internal storage apps i have downloaded it will help me great if you reply to this iam planning to update to 5.1.8 from 5.1.6

Yes almost. After rom installation you flash twrp.zip and reboot recovery and then magisk.
I did it that way some hours ago and did not loose data.
Sorry: had to edit 2 times.

1) download full zip (with oxygen updater or here on the dedicated section)
2) flash via twrp (wait and don't panic it takes some time)
3) instantly flash twrp.zip
4) reboot to recovery for auto switching slot
5) flash magisk
6) reboot to system
7) you're updated/rooted with twrp

how to root 9.0.3 after update which made me loose root

I had root on 9.0.2 did an full OTA 1,5gb even did install magisk on the second slot before rebooting the update. I tried using the one plus one click root tool but that's not working either. Does anyone has an idea what I'm doing wrong ?

I am still on 9.0.2. So can I download the complete stock rom.zip with blu_spark.twrp.img and boot into it via shell comand on phone and then flash the update , reboot the recovery and then the magisk?
Just Flash the full update in twrp following flashing twrp again before you reboot.
Also I would recommend to not reboot to system then, instead reboot to recovery again and flash full update + twrp again, this time also magisk and then reboot the system.
This way you have updated and rooted both slots and have twrp in place

rooting issue. oneplus 7 pro (pie)

i am trying to root and install TWRP on my oneplus 7 pro (9.5.11.GMA21AA gm1910) but its always reverting back to stock recovery. i dont know why or what step i am missing or messing up on.
heres what i am doing:
Code:
fastboot boot twrp-3.3.1-70-guacamole-unified-Pie-mauronofrio.img
then in TWRP i am sideloading the TWRP installer via advanced--sideload
Code:
adb sideload twrp-3.3.1-70-guacamole-unified-installer-mauronofrio.zip
then after that i do the magisk20 (also sideload) which is successful.
Code:
adb sideload Magisk-v20.0.zip
then i reboot the system and all is well. magisk works and passes safetynet.
but when i reboot into recovery it goes to the stock recovery and not TWRP.
whats going on? what am i doing wrong?

You say that Magisk works fine. Flash twrp.zip with Magisk > Modules. Reboot to recovery with Magisk. Flash Magisk again.
Another version. Go to Magisk > Downloads and flash TWRP A/B Retention Script.

Unable to flash TWRP. Lost Recovery, OS and only have unlocked bootloader.

Hi,
I was on Oxygen OS 10.0.0. Rooted with twrp-3.3.1-4-enchilada and magisk 20.1. (I had used this guide to do it. https://forum.xda-developers.com/oneplus-6/how-to/how-to-flash-twrp-magisk-android-10-t3988213) Today I downloaded the zip for 10.0.1 from the Oxygen Updater app and tried to flash it like I have done for OOS 9 in the past as usual. I went to recovery (I did not backup), I just wiped my data (not internal storage), cache and system. After that I tried to install the new zip but I got an error. It just said error unable to install. Didn't mention why. I tried flashing the older OOS 10 zip and got the same error.
So I thought I will try flashing on the other slot. I was on slot B. I switched to slot A and got the same error.
So I thought I will try to sideload. When I tried that I got the same error. So I thought I will try to reflash the twrp img itself. I went to fastboot mode and tried runnning this command
fastboot boot twrp-3.3.1-14-enchilada-Q-mauronofrio.img
It showed me this error
Sending 'boot.img' (65536 KB) OKAY [ 1.609s]
Booting FAILED (remote: 'unknown command')
fastboot: error: Command failed
Now I don't have any recovery at all. I have just the unlocked bootloader and no OS nor recovery. What can I do to flash TWRP again and install either OOS 10.0.1 zip or 10.0.0 zip? Any help will be great.
Thanks

So basically what happened there is TWRP doesn't boot with the oxygenos 10 bootloader. You will need to use the MSM download tool to unbrick your device.

But how is that? I was on stable OOS 10 before rooting following this link https://forum.xda-developers.com/oneplus-6/how-to/how-to-flash-twrp-magisk-android-10-t3988213. As per this, the first step is to flash twrp and that image did flash back when I did it. Any idea why it doesn't work now?
Also, do you have any links for the MSM download tool and any guide if there is?

The problem isn't TWRP it's the bootloader. That's all I know. And for the MSM download tool. See attached link below.

Do not boot the twrp from fastboot it won't work
Just do
Fastboot flash boot twrp.img
Then reboot the device to twrp it will boot to trwp and then flash the new a10 zip and immediately afterwards flash the twrp zip

This doesn't work. It flashes successfully but when I select Reboot Recovery and press the power button, it boots back to the bootloader.
Maybe wrong twrp img
Try the older 3.3.1-12 twrp.img and then try
Also try the following as well
Fastboot flash boot_a twrp.img
Fastboot flash boot_b twrp.img
And try just reboot not reboot to recovery

Thanks so much for that! I have been able to recover the phone using MSM download tool. Now will update to 10 using the phones OTA.
However, I have one question, if I update to OOS 10.0.1, do you think this original post on rooting OOS 10, will work for it? https://forum.xda-developers.com/oneplus-6/how-to/how-to-flash-twrp-magisk-android-10-t3988213 Or do you suggest to not root and wait?

Put the TWRP zip and stock boot img on phone (a TWRP img is not a TWRP zip)
Remove Magisk modules first to avoid issues (in TWRP if you cannot boot to system. https://forum.xda-developers.com/showpost.php?p=72542167&postcount=242)
Update through local update to 10.3.2 is what I prefer to do. Then I do the following.
Reboot to let phone finish whatever. reboot into bootloader.
1. Fastboot TWRP img - fastboot flash boot twrp-3.3.1-18-enchilada-Q-mauronofrio.img - ( https://sourceforge.net/projects/ma...3.3.1-18-enchilada-Q-mauronofrio.img/download )
2. Use volume up to recovery and power button to boot to recovery
3. Flash 10.3.2 stock boot img while in TWRP (or current ROM stock boot img).
4. Flash TWRP zip while in TWRP (https://sourceforge.net/projects/ma...-enchilada-installer-mauronofrio.zip/download ) or Blu zip (https://github.com/engstk/android_device_oneplus_enchilada/releases)
5. Reboot to recovery
6. Flash Magisk 20.3 while in TWRP
(Flash a Q kernel if you want one other than stock)
7. Reboot system
You are now rooted

I had similar situation last evening.
I made the mistake of having a factory reset on rooted 9.0.8 and then trying to flash the 10.0.1
I got the same error, so I had to connect my mobile to my laptop, fastboot to the newest TWRP, flash the TWRP, flash the 9.0.9, flash the 10.0.1, flash magisk 20.x and then everything was working.

This worked for me.. Finally. PS - I did in a slightly different order. I installed twrp first, booted into twrp, made sure I was in slot A. If I wasnt, I rebooted to recovery. If I still wasnt I set slot to A manually then rebooted to recovery again. Flashed the stock boot img you linked to boot, then rebooted to recovery slot b (same process I did to get to slot a) then flashed the stock boot img to boot again THEN finally installed magisk. Booted to system, where it hanged a bit, rebooted before getting into android, but booted in just fine after that..
For some reason if you don't flash stock img to slot A (and maybe slot B too, I did this for good measure) before installing magisk everything dies a horrible death and breaks, which can't even be recovered from /boot /system backups..
EDIT: Tried to reboot into recovery, which reverted back to stock for some reason after doing the above steps. So I proceeded to install the bluspark recovery, rebooted into recovery, made sure I was in slot b, made a back up of the boot image, then flashed bluspark kernel. Got stuck at the unlocked bootloader screen. Rebooted into recovery, restored my /boot back. Still stuck when I try to boot into system. Fixed it by booting back into recovery in slot A flashing stock boot img, then into slot b stock boot, then magisk, but also installed bluspark kernel here because I had a feeling I would lose twrp from flashing to stock boot img, and that the issue was caused by twrp (both twrp-3.3.1-16-enchilada-installer-mauronofrio and twrp-3.3.1-x_blu_spark_v9.108_op6 have this issue). Guess what? Turns out I was right. Having twrp breaks everything after you install magisk, so you need to flash the stock boot img before flashing magisk for some reason.. and cant install twrp again unless you dont mind bricking your phone.
EDIT2: F2FS works, just boot into recovery via fastboot (this should be slot b), change /data to f2fs, boot back into fastboot then into recovery again by fastboot (slot b again), flash stock boot img > magisk > bluspark kernel > f2fs_fstab.zip > f2fs_optimize.zip > factory reset/wipe (from twrp before rebooting), done just reboot into system. You of course lose twrp because magisk doesnt like twrp on oos 10.x for some reason, and will need to set everything up again to cause of the wipe. If you dont factory reset/wipe from twrp before booting into system your system will crash and reboot every time you boot into android, then have to do all the steps I listed again.
EDIT3: Never mind, I was wrong, f2fs makes almost all your apps and storage unusable. Not sure if it's cause of the rom (OOS10.3.0) or because we have to flash stock boot.img and get rid of twrp before booting into system. Either way, f2fs has never really been stable or fun to get working so better to stick to ext4.. that few percent performance boost isnt worth it.
EDIT4: This is my last update. After experimenting with different things, bricking my phone, restoring it via fastboot rom, many many times, I've verified the simplest and cleanest way to install magisk.. Do note you wont be able to keep twrp.
Method A - If you already have twrp
Boot recovery into slot a, flash your rom's stock boot.img, then boot into your recovery in slot b (dont boot into slot a recovery because slot a wont have twrp anymore), flash your rom's stock boot.img, magisk and (optional) your kernel of choice (or not) in that order, then you can boot boot into system. That's it.
Method B - If you don't have twrp
Boot into fastboot, and from your cmd/terminal run fastboot flash boot yourtwrp.img (I suggest Mauronofrio's twrp-3.3.1-16-enchilada-Q-mauronofrio.img or newer). Use your volume buttons to select boot into recovery. Make sure your active slot is B, (if it isnt, install twrp (bluspark and Mauronofrio's twrp both work great) by zip, then follow the steps above in method A). Once you've verified you're in slot B flash your rom's stock boot.img, magisk and (optional) your kernel of choice (or not) in that order, then you can boot into system. That's it.
Maybe @mauronofrio or @eng.stk can verify why magisk or twrp bricks the system when you install them together on OOS 10.

@mauronofrio wrote the following in his TWRP thread a while ago:
So little update, after some tests i'm sure there is a compatibility problem between twrp and magisk, i was able to get only one of them, so actually i don't know how to proceed, i need to understand if it is a twrp problem or a magisk problem, TWRP is in stand-by for now.
There are not problems on Android Pie, if you need of the twrp on android Q just flash in boot partition the Q .img (fastboot flash boot twrp.img) and then reboot from fastboot in recovery. Before publishing the twrp I had not tested magisk and twrp together.
On Android 10 use only magisk 19.4

Basically worked for me, too, with 2 exceptions:
- this tool to remove magisk modules etc. wouldn't be flashed, always ended in an unnamed error; probably the cause for some other problems?
- flashing boot.img (V 10.3.4 from this thread) didn't work for me, I always ended up in twrp's splash screen
- got it solved by dirty flashing the full V 10.3.4 ROM (again from the above thread)
Many thanks once again!

paranoid Android back to stock 10.3.0?

I'm on the latest paranoid Android beta with twrp and magisk installed, can someone provide me with the steps to flash stock ROM 10.3.0 without losing twrp? I don't mind not being rooted
Thanks in advance!
just download the rom from here
flash it via twrp
then after setting up your device reboot to fastboot mode and boot into twrp image
then flash twrp again( be sure to use the latest twrp image otherwise you will not be able to boot into twrp)
ps i dont now if thats gonna work:
flash the rom via twrp
flash twrp.zip
reboot to recovery and again reboot to system

I would say, from TWRP :
- unistall magisk
- reboot recovery
- flash the rom zip
- flash twrp zip
- reboot recovery
- flash magisk

Sure you can flash it, try 3.3.1-16 !
If you get an error by
Code:
fastboot boot twrp-3.3.1-16-enchilada-Q-mauronofrio.img
try
Code:
fastboot flash boot twrp-3.3.1-16-enchilada-Q-mauronofrio.img
.

Installing custom ROM (Havoc) from scratch

I am going to give it one more go, before I go mad
On the OnePlus 7Pro.
Dirty flash = without wiping anything?
Clean flash = with wiping, but what?
Going to go back to a full stock mode: https://forum.xda-developers.com/oneplus-7-pro/how-to/op7pro-collection-unbrick-tools-t3956595
Then the following steps;
- Unlock bootloader.
- Get the latest version of havoc: https://sourceforge.net/projects/havoc-os/files/guacamole/
- Get Gapps
- Get TWRP
- Get Magisk
- Reboot and use adb to flash twrp.img
- wipe what? Some variations I have come across, so just asking.
- Flash OOS (some say, but which version).
- Reboot to recovery, or flash custom ROM and TWRP.zip?
- flash custom ROM and TWRP on other slot without wiping anything?
- Reboot to recovery.
- Flash Gapps and Magisk (on slot it is on after last reboot, or doesn't it matter?)
- Reboot system.
Follow these steps. they always worked for me.
1. flash twrp.img using adb
2. sideload twrp using adb sideload
3. reboot recovery
4. format data(one where you type YES)
5. reboot recovery
6. flash oos & twrp
7. reboot recovery
8. flash oos and twrp
9. reboot recovery
10. format data
11. reboot recovery
12. flash rom and twrp
13. reboot recovery
14. flash gapps(if necessary)
15. flash magisk(do remember that some roms require first boot before magisk is flashed)
16. dlash dm verity(if you want to stay decrypted).
17. reboot system

Going to try this later, after being out of the game for a while this new "A/B" stuff is just totally defeating me. I've had to restore the phone with that M2M program, or whatever it is called, like 4 times. Ugh. Really miss the old days.
Do step 4 again(format data) if you are still getting stuck on startup or a bootloop, then reboot. That is what I had to do with my Havoc install to get the ROM to boot.

Why are you using adb twice to install twrp on some nonsense that's unnecessary. All your is open cmd in the folder where you have twrp.img or whatever you named it boot to fastboot
fastboot boot nameoffile.img
Flash twrp installer after it boots and you're done.
And before you try to say that commands doesn't work like everyone I'm going cut you off and let you know that it does no problem cause i always use it. You don't need sideload or flash anything with adb. One simple fastboot command will do it.

Thanks for the reply.
I have a few questions, see above in the quote.
Besides that, when I come from stock, do I need to flash the OOS twice on both slots, and if so, why is that?

Same here
With you guys on the "wow this has become a confusing process" boat.
The thing that gets me is with 100% of tuts, they say format data and then say format data again later when I think they mean wipe data the second time. Am I right?
The process even seems more straight forward following the dual boot twrp tutorial.
I don't have a need to update my custom rom yet so I just would like a clear understanding.
Before someone says "well you've already done it" I fluked it somehow. Lol

10. To clarify, yes you have to format(where you type yes)
As far as sideload is concerned, I followed it from a guide written by some dev. But it is not necessary. You may skip it
If coming from stock, you may skip those steps. You just have to ensure that both slots have oos

I tried the same steps for my onePlus 7 but post flashing oos and twrp and all the steps at step 12 while i try flashing custom rom i.e Pixel experience in my case i get the belowmessage
"Flashing A/B zip to inactive slot B .
To flash additional zips, please reboot recovery to switch to the uploaded slot.
Error installing zip file '/sdcard/PixelExperience_gucamoleb-11.0-20210217-1706-BETA-OFFICIAL.zip'
updating partition details......
...done'"
But while doing step 6 i.e flash oos and twrp despite the below message
"Flashing A/B zip to inactive slot B .
To flash additional zips, please reboot recovery to switch to the uploaded slot"
It gets flashed without issues.
Just to let u know my phone got bricked so i installed the official firmware using the below command.
fastboot -w update images.zip
Any help on this will be appreciated as i m kinda stuck with the stock rom.
